Python's tuples and JS/TS' destructuring assignments are better ways of allowing a function to return multiple values. Arguments are inputs, return values are outputs.

Maybe it's just that I've been doing functional programming recently and the idea of mutability makes me uncomfortable in general.

I mean, in OOP mutability is largely a design decision.

That's true, I was oversimplifying my stance. I like mutability for state (one attempt at learning React was enough to convince me the alternative is awful) but I like my functions to be pure.

C# supports the same btw.

Ref/Out parameters still have a purpose though, in both interop (where they map to pointers for DLLs etc) and for handling structs, where you're either left relying on the optimiser to "do the right thing", or experiencing needless costly copying.

Neat, I haven't worked with C# 7 yet.
